I had this exact problem on my 01 Dodge Dakota r/t 5.9, it turned out to be my water pump. When i started evaluating the issue i noticed that the belt on the front of my water pump was not staying straight and steady, it would wobble a little left and then a little right, hence why the water pump was not spinning fast enough to cool and when you accelerate it makes that pully spin faster and cool down. Good Luck, Nathan

Why a car overheats when driving but cools at idle?
check your fluids it is probably low on antifreeze and if it still does it change your thermostat that should fix the problem
Your 2000 Durango 4.7L runs a good temperature while driving but overheats when in idle Have replaced thermostat flushed rad and no fluid loss Why overheat in idle?
Wouldn't be your thermostat, its going to be the fan motor for your cooling system. Because the wind that hits the motor while driving cools the motor but when you come to a stop and idle there isn't anything to cool the motor
1993 roadmaster overheats and then cools down?
I would guess that the thermostat is not opening at the proper temperature. Once it does open proper circulation brings it down to the correct operating temperature. I think it should be replaced.
Your kia sportage overheats at stop and go but when you drive it a few blocks it cools back down?
You might want to check and see if the electric coolin fan is working. Also it could be your thermostat not opening and closing when it should.
How do you replace the engine temperature sensor on a 99 Chevy Malib antifreeze is not reaching the engine and it overheats after 20 min but will restart when cools down?
What makes you think it's the temp sensor? It sounds more like a stuck thermostat, faulty water pump or plugged radiator.
Where is the thermostat on a 2004 ion The car overheats while idling but cools down as we statrt to drive on or turn on the defroster?
Thermostat should be located in the removable housing at the engine end of the upper radiator hose Radiator may be clogged or flow restricted the defroster kicks on your electric radiator cooling fan--bypassing your fan relay and temp. switch--so its probably one of those
Nissan Quest 1995 it overheats after driving for a few miles them it cools down to normal but the heat wont work well i should say it works for a few minutes then it blows cold then it goes back to WA?
Is your radiator full? Have you got a leaking head gasket?
Car overheats cools when slow down?
If it overheats at speed, but cools down when you slow down, the problem is likely a head gasket. Combustion gasses are leaking into the cooling system, adding bubbles (which take the place of coolant) and extra heat. Slowing down means the engine is spinning slower, and less combustion gas gets into the cooling system.
Why does my truck overheat and then when I set the heater to defrost it cools down?
Check the thermostat or the radiator. The thermostat could be sticking or the radiator could be plugged.
Engine overheats but then cools back down after a couple seconds on your 1995 S-10 Is that a sign you need to do something with the radiator or is the thermostat going out or what?
I added some coolant to bring it up to the add line...vehicle hadn't been started all day. I will take it out tomorrow and see if it continues to do this. I may need to get a new thermostat. Check coolant level May be a defective radiator cap Radiator hoses may be collapsing under load Gauge may be defective and/or also below answer That sounds like a sticking thermostat.
Why does the AC get cold when driving and warm when stopped in muy 2001 eclipse RS?
Because there is not enough air flow over your condenser (the part that takes the heat away from your car) when your car is stopped but when you start moving again the air circulation gets better so the car cools off
Your 19989 Chevy venture van temperature gauge heats up when the heat when the heat is not on it cools down when the heat is on what is the issue with the vanis it the fan or the thermostat?
